Five female health workers involved in Pakistan’s polio eradication efforts were gunned down Tuesday in two of the country’s main cities amid militant resistance to immunization campaigns.

Unidentified gunmen killed four of the women in Karachi and a fifth in Peshawar. Two male volunteers were also injured in Tuesday’s attacks, according to Sindh’s health department. As a result, an ongoing polio vaccination campaign has been suspended throughout Sindh Province, according to the department.

Tuesday’s violence highlights a new trend of deadly attacks targeting women, who had previously been avoided unless they were members of religious minorities, says Jameel Yusuf, the former head of Karachi’s Citizens-Police Liaison Committee.

Backasswards. Shooting people trying to prevent the spread of preventable diseases? Shooting school girls for getting educations? Yet, some still play the moral relativism game with Sharia Law and radical Islam? Shameful!
